Can Tik Tok group purchase coupons be used by others?

You can. Oh, it's equally effective. The group purchase coupon only needs the serial number information in the short message content, and it doesn't matter whether it is forwarded or not. Therefore, sending a message to a friend only needs to be forwarded, and even without sending a message, the serial number or password of the group purchase coupon in the message can be recorded to the other party for normal use.
